Background: Congenital cardiovascular disorders were found in swine population with a frequency of 0.49-14.6%. The most common developmental abnormalities of the heart in pigs are tricuspid valve dysplasia, atrial septal defect and aortic valve stenosis. Objective: The aim of this report was presenting a case of atrial septal defect with high prevalence in a large-scale pig herd. Materials and methods: South Transdanubian a large-scale pig farm elevated death rate was found among new-born piglets in a large scale pig farm in South Transdanubia. The entire litter or most of the litter died suddenly within a week after birth, without any clinical symptoms. In the farrowing unit, hygiene, feeding of the sows, supply of water, room temperature were optimal. The placement of the newborn piglets, the provision of the heat requirements and colostrum intake were adequate. Thirty five 1 to 4 day-old piglets were dissected. Among them, 25 piglets (20 male, 5 female) showed morphological signs of mild to severe circulatory disturbances. In all cases, the heart was enlarged and slightly rounded. The atria were enlarged, the wall of the right ventricle was thickened, and discontinuity in the septum separating the atria was found in each cases. Atrial septal defect was diagnosed. No PCV2, PCV3 or parvovirus was found by PCR. Results and discussion: Based on the large number of carcasses, atrial septal defect was responsible for the death of more than 50% of piglets. Congenital heart defects are significant not only because of the effects they cause, but also because they can be passed on to offspring through breeding, thus affecting the entire population. In addition, congenital heart defects have been shown or are suspected to have a genetic background. In the knowledge of diagnosis, the management of the farm informed the boar farm from where the sperm was purchased. There is no information about the changes there, but after the information was given, the cases of atrial septal defect that caused death disappeared, and the death rate in the herd fell below 10%.

| Abstract (Hungarian): |
Sertésekben a szív leggyakoribb fejlődési rendellenességei a tricuspidalis billentyűdysplasia, a pitvari septum defectus és az aortaszájadék-szűkület. A szerzők egy nagyüzemi sertésállományban az újszülött malacokban elhullást okozó pitvari septum defectus halmozott előfordulásáról számolnak be. Szuperszapora kocát tartó nagyüzemi sertéstelepen hirtelen megemelkedett az elhullás az újszülött malacok között. A szaporítóanyagot kantelepről vásárolták. A megszületett malacok közül vagy az egész alom, vagy egy részük a megszületés utáni héten klinikai tünetek nélkül elhullott. A boncolt 35, 1-4 napos malacból 25-ben pitvari szeptum defektust diagnosztizáltak. [ABSTRACT FROM AUTHOR] |
